Temperature‐Modulated Selective Detection of Part‐per‐Trillion NO2 Using Platinum Nanocluster Sensitized 3D Metal Oxide Nanotube Arrays

“…Thus, they are playing the critical roles in a smart and sustainable city for safety and healthy monitoring. [19][20][21][22][23] However, the poor limit of detection (LOD) and selectivity are the two main bottlenecks limiting their wide application. [24,25] Well-established methods were utilized to improve the gas-sensing performance, [26,27] and earlier works have demonstrated that LOD of chemiresistive gas sensors can be improved by employing low-dimensional and nanostructured materials with high surface-to-volume ratio.…”
